If you have a nameserver on the host listening on localhost and Docker copies that configuration into the container, then the container will look in its own network namespace for the nameserver. What are the contents of your /etc/resolv.conf file on the host and in the Replicated container?

Could you check on the machine that isn’t working if there are any configurations in /etc/docker/daemon.json or if there were any different flags passed to the Docker server with ps auxw | grep dockerd ?

I am a customer experience engineer with GitPrime and I’d like to take a closer look at the issue you are having. Would you have time for a video call/ screen share with us? You can email me directly at [email protected]
